We purchased a 2018 Tundra in March of 2018, and the lower portion of the body panels on both sides are starting to bubble off from the panels in several places; the paint is actually separating from the panel in fairly large1-1/2" diameter bubbles. I read an earlier post that there is a gravel guard under the paint that gives a rough finish to the bottom of the panels, but this is a paint problem. As of Jun 3 2021 the truck has 39000 miles on it and is still under warranty. I am arranging to see the Toyota dealership this week, but has anyone else had this paint problem?

It’s a stone guard applied at the factory. My truck has it the entire length on both sides. You probably just never noticed it

No, these are larger air-filled bubbles of paint completely lifting off 1/8' to 3/16"" from the panel. I'm aware of the stoneguard, but this is paint that is lifting off of the stoneguard and underlying panel. I originally noticed the stoneguard, with the slight orange-peel effect, but this bubbling in several areas that has recently shown up and seems to be from failed paint adhesion.

Then take it in?

At first it looked like the stone-guard, which catches a lot of people off guard.

That does indeed look like peeling paint.

Do you use a powerwasher and get close to get the dirt off the rough stone-guard area?

I only ask as the bubble I see has what appears to be two holes towards the top. A rock chip, then hit with high pressure a little too close can cause the paint to do that. Normally it just starts peeling, but I could see it blistering instead over time if it holds the moisture in.

Post your findings after you talk with the dealership if you would... I'm interested in what's causing it.
